D.dilation changes the size is your answer. Hope this helps!
See attached for a sketch of some of the cross sections.
Each cross section has area equal to the square of the side length, which in turn is the vertical distance between the curve y = √(x + 1) and the x-axis (i.e. the distance between them that is parallel to the y-axis). This distance will be √(x + 1).
If the thickness of each cross section is ∆x, then the volume of each cross section is
∆V = (√(x + 1))² ∆x = (x + 1) ∆x
As we let ∆x approach 0 and take infinitely many such cross sections, the total volume of the solid is given by the definite integral,

Answer:
72.5mph
Step-by-step explanation:
There is an easy way to work this. Divide the miles he drove by 2 so that you know how much he drove in 1/5 hours.
29/2= 14.5miles driven in 1/5 hours
Now, just multiply that number by 5 so that you know how many miles he drove in 5/5 hours (one full hour).
14.5*5= 72.5miles
